Introduction

This Wi-Fi Shield utilizes a ESP12 Wi-Fi module to provide your Arduino/ Catduino with serial Ethernet's function. Carry on an independent antenna makes it easily to cover wider range and transmit more stronger signals. For the support of TCP, UDP and FTP communication protocols, this Wi-Fi Shield can meet the needs of most wireless network projects, such as smart home networks, robot controls and personal weather stations, etc. We prepared an easy and convenient command set for this shield so that you can use neat and concise code to run the function. If you use the Wi-Fi function, it takes two pins to hook your device up to 802.11b/g/n wireless networks. If you use the storage.
